[vtkusers] [Insight-users] Volume calculation of 3D convex hull generated by vtkDelaunay3D

[Karthik Krishnan]

If you are indeed generating the convex hull, your result is entirely
composed of tetrahedra. Iterate through all the cells and use the method
vtkTetra::ComputeVolume to sum them up.

You should have only tets, unless you have alpha != 0, (in which case, you
won't have the convex hull anyway)
